Embedded Interactions and Selective Disclosure: Network Effects on Conversations aboard Skylab

Symbolic Interaction, EarlyView.
How do absent others influence our interactions? We argue in this paper that interactions are embedded within networks formed by chains of specific relationships between known third parties. The anticipation of future interactions with external others conditions our interpretation of the current situation and affects our behavior in the interaction. We

Spiral Approach for Non‐Software Product and Engineering System Development

Systems Engineering, EarlyView.
ABSTRACT This article explored the spiral development process, sometimes called “evolutionary acquisition” in military sectors, and reviewed major non‐software applications in the engineering literature. The spiral development process was originally developed for the design of software while minimizing and managing risk, but the principles can be ...

Lightning‐Induced Overvoltage on Overhead Distribution Line via Hybrid MTL‐PEEC Method

High Voltage, EarlyView.
ABSTRACT Transient simulation are more economical and adaptable means of studying lightning overvoltage for overhead distribution line system compared to experiments. A hybrid multi‐transmission‐line (MTL)‐partial element equivalent circuit (PEEC) method proposed for lightning‐induced electromagnetic pulse (LEMP) simulation is verified using the rocket‐
